.L'FJECEFECATION forming part of Letters Patent No. 341,903, dated May 18, 1886.

Application filed May B, 1885. Serial No. 164,755. (No model.)

.To all whom it may concern:

Be it known that I, ALBERT H. GREEN, of Le Roy, in the county of Genesee and State of New York, have invented a new and useful Improvement in LettenFiles, which improve ment is fully set forth in the following specification and shown in the accompanying draw ings.

The object of my invention is to produce a convenient letter-file, the same being constructed of parts combined and arranged sub stantially as hereinbclow specified, and more particularly pointed out in the claims.

Referring to the drawings, Figure lis a vertical transverse section ofthe case of the letter-file, taken as on the dotted line x in Fig. 3, and viewed as indicated by arrow in said lat ter figure, drawn to show the interior working parts of the same, parts being shown in full and dotted line positions, land the portfolio omitted; Fig. 2, a similar view of the operating parts of the same, showing another man- 11er of expanding or opening the month of the case, parts being shown in two positions by full and dotted lines; and Fig. 3 alongitudinal vertical section of the case, taken on the dotted liney in Fig. l, and viewed as shown by arrow in said latterfgure, drawn to further show the parts within the case.

Referring to the parts, A is the case of the letter-file, preferably made of substantial paste board, formed of suoli size two ways as to hold without folding common lettersheets, and of such thickness as to receive a portfolio with as many or more pockets or apartments as there are letters in the English alphabet. The case A is composed of two main parts, B and O, one lapping or closing over the other, both together forming tive sides of a complete rectangular inclosure or prism, said parts being connected by a hinge-joint at a along the horizontal lower front corner of the case. Then thus joined, the open sides of the parts B and C- are turned toward each other, the part C forming in part a cover for the part B, closing over on the outside of the same, and covering the broad open side thereof.

The main part l5 of the case is made up of the back sheet of pasteboard, I), bottom sheet, o, and two similar and equal end or side sheets, d d, all secured together to form a rectangular inclosure, within which the portfolio E rests.

The otheror lesser part, 0,01g the case is made up of a front sheet, e, similar and equal to the sheet I), above mentioned, and two sides or end sheets or flaps,` f f, similar1 and equal to the' sheets d d, above mentioned, save that they are cut across obliquely at the top, as shown by dotted line g. The sheets e and f f are `joined to form three adjacent sides of a rectangular inclosure, a little wider than the inclosure formed by the sheets b c and d d, above described, so that when the two parts B and G are put together to form the case A, as shown, the sheets ff will close or lap over or on the outside f the sheets d d, making the end walls of the case of two thicknesses, el and f.

Near the bottom of the case each sheet d is formed with a short circular slot, h, concentric with the hinge-joint a, and a stud, t', transversely sectioned in the gnre, is secured rigidly tothe inner face or surface of each adjacent overlapping sheet f in position to reach through a slot, h, and receive at its inner end a simple head or button, (Shown in dotted circle in Fig. l.) rIhese studs and buttonsone on each side of the case-serve to hold the sheets f f at theirlower ends in place against the respective sheets d d. Near the upper part of the case a longer circularislot, 7c, is formed in each of thesheets d (l, concentric with the joint at c, with a similar stud, o, secured to each sheet f f, and projecting through the respective slots k, with a thin but-ton, r, (shown in dotted circle,) at the inner end of each, which serves to hold the upper ends of the sheets f fsnugly against the end sheets, d d, of the part B. The slots h and r, being concentric with the hinge-joint at a, permit the part C ofthe case to be swung or tipped back away from the part B, as shown in dotted lines.

The cover D of the case is held. by a hingejoint, Z, to the part B, and when closed laps down over the outside ofthe part G, and thus holds the parts B and C together, altogether forming a comparatively perfect inclosure for the portfolio and letters within.

In Fig. 1 is shown a thin vertical disk, p, pivoted on a pin, s, projecting horizontally inwardly from the inner face of the sheet d, midway between the front and back sheets, b and e. rlhe disk is formed with a radial slot, t, in position to also receive through it the stud o,

the button r, above mentioned, being on the IOO inner face (the one seen in Fig. l) of the disk.

Bearing in mind the fact that the stud ois rigid with the sheet f, it will be understood that if the disk be turned upon its pivot in 5 the direction indicated by the arrow thereon the part C of the case A will be forced back to the position indicated by dotted lines-that is to say, the mouth of the case will be expanded to assist a person to more readily get lo at the contents of the case. A bent connecting-strap, u, is pivoted at one end ata to the disk, and at the other end tothe inner surface of one side of the cover at a in such position that when the cover is opened it will turn the I 5 disk and automatically expand the mouth of the case, as stated, and when closed will act in the opposite direction and contract the mouth of the ease. Thus by simply opening or closing the cover, the case of the letter-file Will be expanded or contracted i,n a desirable manner.

It is designed to have one of the automatic openers and elosers at each side of the ease to operate the part C alike and evenly at both 25 sides.

In Fig. 2 is shown au elastic eord, I/, passed around the buttons c e and d', the two former being secured to the sheet d, and the latter to the sheet f by means of a stud, f', passing through a slot, e', in the sheet d, similar to the 3o slot kin Fig. 1. As arranged, the tendency of the cord is to draw the button d toward the buttons c c to the position shown in dotted lines, in which position the mouth of the case will be expanded, as above described. This serves to expand the month of the case, when released, by opening the cover of the same; but in this construction the case has to be contracted by a pressure of the hand When it is wished to close the cover.

lhat I claim as my invention is- A letter-file case consisting of the part B, formed with slots e', and provided with buttons c, and the part C, provided with studsf, passing through said respective slots e', and buttons d, held at the inner end of the respective studs f in line with the buttons c', said parts B and C being joined by a hinge-joint, a, in combination with elastic cord b', passed over said buttons, substantially as and for the pur- 5o pose set forth.
